Design of Highway Alignment

In this post, we are examining the Importance of Highway Alignment and different elements which should have been considered in arranging the highway alignment. The Terms which we talk about here are the most significant and typically go over in highway structuring and arranging. As a structural designer, you should know about these terms. When the arrangement of road construction is chosen, the following stage to chip away at is the highway alignment.

What is Highway Alignment: The situation of the focal line of the highway or the design of the arranged highway line on the ground is called Highway Alignment. Highway Alignment is for the most part stated as two sorts on Highway plans.

Horizontal Alignment: This covers the horizontal way of the road either it's straight or curved or both. Top perspective on road alignment gives horizontal alignment of the road.

Vertical Alignment: This arrangement with the inclinations, slopes and leveling of the ground. Viewpoint view or front view or side perspective on the road alignment causes you to comprehend about Vertical alignment.

Significance of Highway Alignment: Choosing the highway alignment is the most essential piece of road construction. Road construction includes a ton of land securing. When the alignment is fixed and built according to design, it is hard to change it in view of addition at the expense of connecting the area and advancement of costly structures by the roadside. A little mistake in the Highway alignment improves the expense of construction.

The perfect Highway alignment should meet the accompanying rules as follows.

1. The alignment ought to be structured so that the distance between the beginning point and the endpoint of the road ought to be short and straight with fewer curves.
2. The alignment is chosen so that it ought to be anything but difficult to build and keep up. A decent alignment ought to be direct and have less angles and slopes. To accomplish this, a little deviation in alignment is allowed.
3. The alignment ought to be viewed as just when the activity cost, introductory expense and upkeep cost is least.
4. The choice alignment ought to be sheltered during construction, particularly at banks, slopes, bumpy regions and at inclinations.

Components controlling the Highway alignment

Obligatory Points: The control focuses administering highway alignment are called obligatory focuses. These focuses choose where the alignment should pass and where the alignment ought not pass.

How to design tensile strength of angle section according to IS Code 800-2007

This is another useful presentation from the eminent civil engineer Mr. Parag Pal. In this video he shows the essential method to create the design of tensile strength of angle section ISA 9060 with thickness 6 mm as per IS code 8000-2007 limit state method.

Tensile strength is a vital attribute of concrete as concrete structures are extremely susceptible to tensile cracking owing to different types of effects as well as applied loading itself.

Tensile strength of concrete is very low with reference to its compressive strength.

Because of the complexity in employing uniaxial tension to a concrete sample, the tensile strength of the concrete is defined with indirect test methods like split cylinder test and flexure test.

It must be remembered that above methods provide the greater value of tensile relating to the uniaxial tensile strength.

Tensile strength calculates the force necessary to pull a structural beam to the point where it cracks.

The tensile strength of a material refers to the maximum amount of tensile stress that it is based on prior to failure.

The definition of failure differs in relation to material type and design procedure.

Watch the following video tutorial, to learn the design process for tensile strength.

Learn to compute cement quota, brickwork volume & no. of fixes for a brick wall

This construction video tutorial will show the details of cement quota, brick work volume, number of fixes for a brick wall construction.

To calculate the brickwork volume, just apply the following formula :-

Total brickwork area x wall thickness
= 31.98 x 0.2 = 6.38 m3

The ratio of cement & mortar needed in brickwork is 1:3 (it can also be taken as 1:5 and 1:6).
Volume of brickwork = 6.38 m3
For 1 cubic meter of cement mortar, the volume of sand will be 0.2m3
For 6.38 cubic meter, the volume of sand will be 6.38 x 0.2 = 1.276 m3

For 1m3 cement mortar, the volume of cement will be = (0.2x1440)/3 (3 denotes last digit of ratio)
= (0.2 x 1440)/3 = 96 KGS
For 6.38 cubic meter, the volume of cement will be 6.38 x 96 = 612.48 KGS

To work out the number of cement bags, just divide it by 50 (as weight of 1 cement bag is similar to 50 Kg)
Therefore, 612.48/50 = 12.24 bags = 13 bags (approx.)

Some useful construction tips to provide clear cover for reinforced concrete structure

This construction video tutorial will provide detailed guidelines on how to provide perfect clear cover in reinforcement concrete structure.

With the intension of safeguarding the reinforcement from corrosion as well as arranging fire resistance to bars implanted in concrete, clear cover is set for Reinforced Concrete Structures.

Clear cover stands for the distance among C.G of reinforcement bars and bottom most point of concrete.

The thickness of cover is dependent on ecological conditions and nature of structural member.

The depth of concrete cover is calculated by applying a cover meter.

The clear cover that should be provided is determined by Indian Standards. IS 456:2000.
